In 2019 tools and software development best practices have evolved to the point where humans and the machine can truly meet in the middle. #STRENGTHS FINDER CODE GENERATOR FULL#Who wants to work on code that was spit out by a machine when it is full of obscure techniques and mangled variable names? The generated code of yore was just demoralizing and sad, and just nothing you would want to build upon. Sadly, the history of the Software industry is littered with examples of code generators, code-free development tools, WYSIWYG front end generators and haunted by the general horrors of cryptic source code spit out by venerable platforms that never seem to die ( I am looking at you DreamWeaver Ultradev or should I say Drumbeat 2000?!).ĭrumbeat 2000 was bought by Adobe and lived on folded into Dreamweaver (amazingly info on “DB2K” does not seem to be in Wikipedia) This type of Dynamically generated code is exciting because not only does it save us time and money in developing in writing code manually, but it provides an opportunity to create responsive behavior in our application at runtime without human intervention - and potentially based upon AI decisioning - making our apps and digital experiences more engaging and useful than ever. Interestingly, these classes can be compiled in memory and loaded by the classloader without ever being written to disk.Īnd they say that Java is not a dynamic language! #STRENGTHS FINDER CODE GENERATOR GENERATOR#Running code can be “self-aware” via introspection such as with languages like Java and the Java Reflection API and Ruby Metaprogramming the options to build truly dynamic applications really expand once your code becomes self-aware.Īt Starter we used Java to build the StackGen generator engine which meant we were able to use the convenient JavaPoet library to dynamically construct Java class files including functionality that is dynamically synthesized during runtime. Templating is not the only approach to code generation. ![]() On the server template engines such as Velocity as well as server-based implementations of mustache and handlebars spit out pre-rendered source files such as HTML and increasingly JavaScript. HTML templating and popular new static site generators all leverage template parsing typically using the popular mustache or handlebars template engines. Other template-based code generation is rampant throughout the software industry. The React ecosystem has been especially active in creating template-based application frameworks including React’s “create-react-app” CLI command. Letting computers do the dirty work? Sweet! Template-Based Generation The famously odd Project Lombok basically rewrites your Java code as you type, generating phantom methods so you can focus on greatness.Īnd as any good JavaScript dev can attest “transpilers” like Babel rewrite your advanced ES2017 into dumbed down 10 year old browser-compatible JavaScript so you can write modern code without worrying how the browsers will behave. One extensive form of automated coding is Code Rewriting - used to convert one language version syntax to another, and sometimes to another language entirely.įor example languages such as Scala essentially rewrite your code into Java-compatible code under the hood. ![]() So let’s take a look at the Turkeys, Ducks, and Chickens involved in the code generation menagerie… Code Rewriting Like some kind of vast digital Turducken, REST APIs and their generated clients are seemingly capable of connecting anything to anything. The explosion in the sheer number of REST apis has resulted in a bevy of API client generators for any number of programming languages and environments being developed during the past decade. ![]() ( Full disclosure I am the developer of StackGen.) Today, code generation happens at every layer of the software stack, including Java libraries such as swagger CodeGen, the latest crop of cross-compilers/transpilers like Babel for JavaScript apps, and full-stack generators such as Starter StackGen(tm) which combine both. The current state (Spring 2019) of code generation is that it is everywhere. Connecting Everything to Everything is Just the Beginning… The Current State of Code Generation ![]()
